Gronk’s gonna Gronk … but he apparently started doing so long before he was spiking footballs.

During the “Thursday Night Football” matchup between the New England Patriots and Miami Dolphins, CBS aired video of 5-year-old Rob Gronkowski laying the hammer on a piñata.

Gronk, seemingly twice the size of his young classmates even then, showed off his terrific hand skills by grabbing a large bag of candy — as well as most of the other good stuff — as it fell out.

Some things just never change, as evidenced by the way Gronk, now a 26-year-old Patriots tight end, dominated the Dolphins on this touchdown in the first quarter Thursday.

It’s Gronk’s world. We’re all just living in it.
